Pit lane mechanics wore white overalls both to make them visible to drivers and also the tight fitting meant there was a greatly reduced chance of the clothing getting caught in moving parts during wheel changes etc. In workshops and Factories the supplied coats (white, brown, blue, grey) often denoted a department or grade (e.g. supervisor, inspector).

In the Jaguar 'Blue' Room (trim shop) the workers wore white aprons. They were issued with two and were expected to take one home and have it washed so they always had a clean one on Monday morning.
